Meant keys got famous (7)
I believe the answer is:
denoted
'meant' is the definition.
(denoting is a kind of meaning)
'keys got famous' is the wordplay.
'keys' becomes 'de' (I've seen this in other clues).
'got' is a charade indicator (letters next to each other).
'famous' becomes 'noted' (noted can mean well-known or famous).
'de'+'noted'='DENOTED'
(Other definitions for denoted that I've seen before include "Indicated or meant" , "Signified" .)
